Inibitorio

Inibitorio is an adjective used in Portuguese to describe something that inhibits, restrains, or reduces activity. In scientific contexts—such as biology, pharmacology, and neuroscience—it designates mechanisms, substances, or effects that decrease the function of enzymes, receptors, neurons, or signaling pathways. The term often appears in phrases like ação inibitória or efeito inibitório.

In biology and medicine, inibitório refers to agents or processes that diminish biological activity, as opposed to excitatory or facilitatory effects. Examples include enzymatic inhibitors and receptor antagonists in pharmacology, and inhibitory neurotransmission mediated by certain neurotransmitters.

Etymology: the word derives from the verb inibir (to inhibit) plus the suffix -tório. The spelling varies by language; in Portuguese the standard form is inibitório, with diacritics, while in Spanish it is inhibitorio and in English the cognate is inhibitory.

Usage notes: the term is primarily technical and common in academic or clinical writing. More frequent nouns include inibidor (inhibitor) for an agent, and the noun phrases efeito inibitório or ação inibitória. The concept of an inhibitory synapse may be described as sinapse inibitória.
